Hi All,

I need to format the table of contents (TOC) in multiple Word documents daily. I'm using Power Automate with OpenXML (C#) to add the TOC. However, the code is inserting a TOC but not update it automatically, as shown in the attached image.

The main requirement is:

If a TOC already exists, it should be updated.

If no TOC is present, it should be inserted.

Note: The solution must work online only.

Is there any other approach to achieve this?

Thanks,

Renjeesh.

I am not sure this will do what you need, but it may give you an idea on how to do what you want. It is for populating a Word document without using the premium populate a Word template action. Based on your description, I don't think using a template would work for what you need.
